There are other studies that have compared the offerings on multiple benchmarks as well. Here's the one I was referring to: https://zapier.com/engineering/quick-redis-benchmark-aws-vs-... see the comparison for yourself on multiple benchmarks.
Many argue that the AWS ecosystem (25 services at last count) and the extensive featureset of AWS outweigh the bare bones "fast" metrics of other providers.
I think like the poster above is mentioning...there is generally more to it than a simple metric or two sampled a few times from a single endpoint. But I guess it all lies on ones definition of what they consider valuable...
